Blacklist the greenlist. I cannot repeat this enough. Do not accept money from them, or send money to them. Do not process their transactions if you mine directly.

How about more meta than that: Whitelisting schemes require you to constantly use whitelisted addresses. Blacklisting schemes are more powerful when the blacklisted parties use constant addresses.

So there is a behavioral difference in transactions which are compatible with a white/black listing broken fungiblity universe: They constantly reuse addresses. Reuse is already a long term known-bad for privacy thing so why not depriortize transactions which reuse addresses?

You want the fastest confirmations? Transact in a way which is not compatible with white/black listing.

And its already a reality: Eligius (15% network hashpower) is now experimentally limiting reuse to once per block.
